10 COMMON ISSUES WITH 1988-1998 C/K PICKUP TRUCKS 

Right on brother, love your story, and thanks for sharing! I remember being so happy to get my truck in a garage. And these are badass amazing trucks. I was just out driving mine today as it's been sitting in the garage all winter looking pretty. Sounds like you got yourself a *sweet GMT400* . I have the best resource anywhere on *GMT400 Upgrades and Performance Parts* . I have a 3K word article that truly covers it all with links to everything. I mean everything. *You should check it out* . It will be a solid resource for you going forward www.buildpriceoption.com/gmt400-upgrades/ and I have *over 60 videos of my truck* and most of the videos are of me doing some kind of fix. Here's the playlist ru-vid.com/group/PLZPFVgOzDxzUNotTlw4KYrOgZebABH3Gg

Got the same truck, same year. I had to replace the entire front end suspension. I feel as though I may also have a gasket leak. I was driving to work in Atlantic City one day. Truck had run fine. Appeared to start to "overheat" and as I was pulling over lost responsiveness in the throttle. Sound like a gasket leak? Great truck tho. South jersey represent!

Same

And that filler panel is just a piece of plastic which easily cracks and breaks if you hit something with the front bumper, as I did once. But those things are now replaced.

It’s a actually up until 2000 then the HD Silverado was introduced in 2001

@@KingStepsideWrong. The C3500HD used the old body style until 2002.

@@KingStepside No not correct, the 3500HD (the real HD truck) was around until from 1991 to 2002. It is a true class 4, 15,000 GVW C&C only, medium duty truck that was eventually replaced by the Topkick and Kodiak C4500 trucks. The Silverado is just a class 2-3 truck regardless if pickup or C&C. GM started to use HD for Silverado as it worked well from a marketing point, nothing more.

open them up and re-solder the broken solder joints and they will be good as new

bruh same lmaoo

It's a long list on these trucks, but we love them anyway. Make sure you take a look at my GMT400 Upgrades and Performance Parts Guide. There's nothing like it online and it's the best www.buildpriceoption.com/gmt400-upgrades/ - thanks for watching!

What do you do for code 42

Thank you for sharing and yes, they are great trucks!

Great tip!

Glad you enjoyed it!

My truck does this

@@deadcalifornia if you call a Chevy/gmc dealership, they’ll order it for you and install it for free if the recall applies to your truck

I bought a 1 owner 1996 Chevy K25004x4 in November 2020. In January took it to dealership for an oil change, they tell me there is a recall on the wiper motor, they had it in stock and replaced it, amazing!! GREAT truck!

@@whitecloudrancharizonatim56 I’ve loved every second of owning mine. Never had any problems and I just hit 140k on the odo. The 5.7 has decent power and torque so no problem accelerating

@@eliweldon9939 nice! I’m at 159k, bought it with 154k, it was owned by Sheriffs Department in Apache County AZ. I’ve serviced all fluids, have brakes and differential fluids to switch and all maintenance will be current. Now of course I have a small leak, looks like rear main seal, but by small leak like 2-3 drops overnight, and some days no leak at all, strange. I’ll have to address it this summer probably, trying to do as much repair and preventative maintenance as possible. But YES, love my truck!

Glad you liked it!

I have an '89 C1500 w/ the 5.0L 305 V8, the problem with mine is after its warmed up, it likes to stall!! Looking at replacing the intake manifold and carburetor and hopefully will take care of that problem! Thanks for the video, very informative!!

Thank you!

That is a correct assumption. I have over 60 videos of the truck and many of those videos are of me doing repairs but not everyone can turn a wrench or wants to. Sounds like you really are a GMT400 fan. Me too. You should visit my website and read my article, *"GMT400 Upgrades and Performance Parts Buyers Guide,"* it IS the definitive resource on all things GMT400. GMT400 upgrades include suspension, engine, interior, accessories, and more www.buildpriceoption.com/gmt400-upgrades/ - Thanks for watching and sharing your knowledge so we can all benefit.

@@BuildYourOwn I'll definitely check it out! To add...5 of my GMT400's had the 4.3L and even with their quirky odd fire (which was only done one other time with Buick and their 225 V6 that eventually became the 3.8 of Buick Grand National Fame), they are and were a dead reliable platform that you could literally put 500,000 miles on with just regular maintenance. Add the 5 speed manual and typically higher rear end gearing and a few tweaks on the top ends and you've got one super odd (see what I did there) sleeper of a truck that still got in the area of 20mpg on the highway. The last 4.3 I owned I passed along to a friend and at last check it's got 423,000ish miles on the untouched except for typical maintenance engine AND 700R4/4L60 Non electronic. Cheers! Zip~

Thank you!

😂

Not really, they last forever.

That statement is not true

Explain those motors are known to get 350000 plus and mine is 96 chevy w/t only 167000 and she gets up and goes Edit:and if you change the oil and take care of it, it will last as long as you my windshield washer still works I got a goodie

💩

I had the same thing happen 1998 C1500 WT, a quick re-flow, and it was a done deal.

Me too..91 ck1500 Silverado stepside..left millions of blackmarks and I just drove it..all I've ever done is changed oil on time,I've replaced a ignition module and window switch..188,000 miles

Nice. I just did another video with the truck and it looks even better in this video though the video is about a coolant leak ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-y2WcdSmwcaE.html

Very true, good point. The passenger door on the truck will act up and that's probably the issue

That's easy....8$ dollar part..tho...

That’s nothing all cars have problems that’s a pretty weak problem

Of course, I hold the C1500 close to my heart as I have a 94. I bet you have a lot of knowledge to share if you've taken your truck apart many times. I have over 60 videos of the truck, many of them of me doing some type of repair or upgrade. *Here's the playlist* ru-vid.com/group/PLZPFVgOzDxzUNotTlw4KYrOgZebABH3Gg - I also put together a *GMT400 Upgrades and Performance Parts* list on my website and it's the best information and resource anywhere around www.buildpriceoption.com/gmt400-upgrades/ - Thank you for watching!

I just had to knock my pins back down lol

So keep those hinges well lubricated, right?

Don't talk about my truck. My truck looks good and EXACTLY the way I want it to look. You can do what you want with your truck, don't tell me what to do with mine. Period.

@@BuildYourOwn SIMMA DOWN BOY

@@BuildYourOwn I think your truck looks great. Then again, half my paint is missing and I think my truck looks great. Just glad to still see so many of them on the road.

@@BuildYourOwn I like your style

@@MrSpikebender Thank you very much, that means a lot!

I'm glad you asked! I've been asked that question so many times I finally made a video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tiE-PvhJDOE.html

My truck does the samething, and then when i shut them off sometimes they will just keep going amd shut off whenever they want.

That does get annoying sometimes.

I'd say it's time to swap out the older style wiper motor for a newer one.

The recall were bad solder joints on the board just pull the board and hit it with the iron maybe even add some solder to the joints and your problem will be fixed took me a minute to remove my board and 5 mins to hit the joints with the iron and put back in and haven’t had a problem since I did that and all speeds work

I got rid of the factory air box long ago for this Edelbrock Pro-Flo ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-cJjahhlD854.html

Rotor wrong position its sounds like must be in exact spot / position it came off of

I have not had any issues like that. Seems pretty good in terms of all that. What I need are some fresh springs all the way around!

The Golden Gate Bridge had to be a horrible place to break down. I had EGR issues when I first got the truck. I haven't had the truck but maybe 2 years and change. The joke is I spend more time working on it than driving it lol. We call it the movie star truck since I do so many videos with it. But it actually runs great and I have come to really love this old truck. Next jobs coming up will be intake manifold gaskets and then a new steering box and shaft to get rid of the play in the wheel. Thank you for sharing your truck. Its encouraging to hear from everyone. Hope you keep watching these truck videos. Have a great day and luckily most of us work in these old trucks as the parts are pretty cheap and the vehicles pretty straightforward

Oh, you should check out LMC truck for parts

@@BuildYourOwn Haha, I have the same joke, but mine is the damn ICM. The problem is, you don't know when will this damn thing goes bad, so when you want to diagnose it, it runs good. But when you assume every thing is okay, go out for driving, it goes bad suddenly. To make it worse, at places that you never want it to happen, the GGB is just one of them, it once happened in a 2-line tunnel without emergency parking line, then one day at center line of a high traffic flow 5-line highway, and almost got rear-ended by vehicle behind when trying to merge to right shoulder. I changed fuel pump, fuel filter, injectors, fuel pressure regulator spring, and then distributor, ignition coil, spark plugs, so I know every hardware for fueling system and ignition system. After changed ICM, the stall problem never happened, but its power is very very weak. After many miles of driving, some reading on service manual, it finally turns out I didn't it wrong when doing ignition base timing. You know there is a ignition wire, should unplug it when doing base timing. The repair manual says the wire is near distributor, but I never found it, then I just assume that cold idle is base time, so the actual timing is about -30 when it supposed to be +4. Then on the internet, I found out the wire is actually inside cab, above passenger's feet, near the blower motor! Then I did find it, unplug it, finished the timing, then every thing goes right till now. Yeah, anyway, working on these old trucks and engines, running between garage and junk yard is a pure fun. Especially 88-95 TBI system, everything is simple and straight forward. Sometime I feel, it's like conquering a good horse. It tries everything to throw you on the ground, but when you finally win, it will be your best friend, honest to you forever. My coming up project, is add second radiator, and electric fan convention, then have someone to reprogram the ECM, add stand-alone TCM. Maybe in the future far away, procharger.

@@BuildYourOwn Checked, looks good, thanks. The website design is quite straight forward.

Sounds like you have some serious experience with these trucks... So let me ask you... I have the 4.3 tbi and I am seriously considering an engine swap, but I want to keep it as simple and straightforward as possible. I've come to the conclusion that I would like to find a 350 tbi crate engine, maybe put some good heads, a performance intake that accepts tbi and some headers and call it a day. I am looking for as plug-and-play easy as possible. I would keep messing with my 4.3L but there are no parts for it. Curious about your input

Same, 4.3 5-speed, trying to work out some gubbins in the rear lights rn, it just gets weirder every time I "fix" something.

And yet we still love these old trucks!

I had the samething happen, after turning the engine off my stereo was still on, the problem was in the ignition so I had to make sure the ignition was off by turning the ignition off slowly! That fixed that problem!!

Try new back shocks. I had same mind of issue putting it in drive. Big clunk. Doesnt do it anymore

@@Trekguythingy I’m pretty sure it’s my rear drum sticking a little

@@micah2395 either a leaky wheel cylinder or axle seal will cause the brake to stick. It will also cause wheel lockup when wet

Please I need some advise if others have had this issue

pins are really cheap and takes mins to do if you got a hand to help hold the door with you

I'm sorry to hear about the issue you're facing with your '95 c2500. Based on your description, it sounds like it could be a fuel delivery problem or a sensor issue. Here are a few things you might consider checking: Fuel Pressure: Ensure that the fuel pump is delivering the correct pressure. A faulty fuel pump or clogged fuel filter can cause these symptoms. Throttle Body and IAC (Idle Air Control) Valve: The TBI system relies on the IAC valve to regulate the idle. If it's dirty or malfunctioning, it can cause idle issues. Cleaning the throttle body and IAC valve might help. Vacuum Leaks: Check for any vacuum leaks, as they can cause rough idling and stalling. TPS (Throttle Position Sensor): A faulty TPS can cause idling issues and stalling. You might want to test its functionality. Check the Distributor: Ensure that the distributor cap, rotor, and spark plug wires are in good condition. ECM (Engine Control Module): Sometimes, a faulty ECM can cause such issues. Check for any stored error codes. Fuel Injectors: Ensure that the fuel injectors are not clogged and are functioning correctly. It's always a good idea to start with the basics, checking for spark, fuel, and air. If you're not comfortable diagnosing the issue yourself, I'd recommend taking it to a trusted mechanic who is familiar with the TBI system. I hope this helps, and I wish you the best of luck in resolving the issue! 🚗🔧👍

@@BuildYourOwn really appreciate the info I actually have change air idle control on other cars and it improved over all reliance on it will have to see if I can clean it or just replace it spark plug wires distributor rotor had work on it before I got it so I kind ruled that out very informative video appreciate the quick response man💯💯

Me too

Enjoy the truck! I've certainly put some money into this truck, but it's been good to me. I've got the 4-inch Rough Country suspension lift (thinking of going up to 6" as I like it so much) and I'm running 17" Vision D Window wheels. The only links I have are to the videos I did getting those products on my truck. Here's the link to the lift ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-W8gQmnaeONc.html and the link to the wheels ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--nARGFsOd7g.html - make sure you checkout my playlist for the truck, the link should be in the description of one of those videos

intake gaskets just under 100 if you do it yourself like i do

and most of that is new fluids motor oil and new antifreeze

3-400 for an alternator hell no lol buy used or good new for 100

The prices are for people that DON'T turn wrenches. More people make this same comment... I have over 60 videos of the truck and most are of me fixing it. Not everyone is so inclined. Its comments like these that make people think you have to be born with a wrench in your hand. You don't. You can also pay someone to maintain it. I'm sure I will hear this same comment very soon!
